<ul>
<li>Start working on CGIAR Library migration</li>
<li>We decided to use AIP export to preserve the hierarchies and handles of communities and collections</li>
<li>When ingesting some collections I was getting <code>java.lang.OutOfMemoryError: GC overhead limit exceeded</code>, which can be solved by disabling the GC timeout with <code>-XX:-UseGCOverheadLimit</code></li>
<li>Other times I was getting an error about heap space, so I kept bumping the RAM allocation by 512MB each time (up to 4096m!) it crashed</li>
<li>This leads to tens of thousands of abandoned files in the assetstore, which need to be cleaned up using <code>dspace cleanup -v</code>, or else you&rsquo;ll run out of disk space</li>
<li>In the end I realized it&rsquo;s better to use submission mode (<code>-s</code>) to ingest the community object as a single AIP without its children, followed by each of the collections:</li>
</ul>
<pre><code>$ export JAVA_OPTS=&quot;-Dfile.encoding=UTF-8 -Xmx2048m -XX:-UseGCOverheadLimit&quot;
$ [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e some@user.com -p 10568/87775 /home/aorth/10947-1/10947-1.zip
$ for collection in /home/aorth/10947-1/COLLECTION@10947-*; do [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e aorth@mjanja.ch -p 10947/1 $collection; done
$ for item in /home/aorth/10947-1/ITEM@10947-*; do [dspace]/bin/dspace packager -r -f -u -t AIP -e aorth@mjanja.ch $item; done
</code></pre>
<ul>
<li>Note that in submission mode DSpace ignores the handle specified in <code>mets.xml</code> in the zip file, so you need to turn that off with <code>-o ignoreHandle=false</code></li>
<li>Give feedback to CIFOR about their data quality:
